본 발명은 폐폴리우레탄(polyurethane)을 재생하여 건축물시공 또는 기 건축된 각종건축물의 단열, 방음등의 효과를 창출하기 위한 폐폴리우레탄을 원재료로한 단열재의 제조방법 이에 의해 제조된 단열재 및 그 제조장치에 관한 것이다.The present invention is a method of manufacturing a heat insulating material using the waste polyurethane to produce the effect of the insulation, sound insulation, etc. of various constructions or buildings pre-built by recycling the waste polyurethane (polyurethane) and the heat insulating material produced by this and the production Relates to a device.
현대산업사회의 다양함에 따라 다양한 산업폐기물이 하루가 다르게 발생하여 많은 공해를 유발시킴으로 해서 수질의 악화, 환경공해의 악화는 물론이고 가정생활에 미치는 악영향 역시 크다.According to the diversity of the modern industrial society, various industrial wastes occur differently every day, causing a lot of pollution, so that the deterioration of water quality and environmental pollution, as well as the bad effect on the family life.
그중에서도 특히 각종가전제품인 냉장고등의 냉장, 냉동기기 및 신발류의 밑창으로 사용되는 폴리우레탄(polurehtane)은 특수폐기물로 분류되어 현지까지 거의 재생불능한 것으로 사용되고 있다.Among them, polyurethane (polurehtane), which is used as a sole for refrigeration, freezing equipment and footwear, such as refrigerators, which are various household appliances, is classified as a special waste and is used as almost non-renewable to the site.
이러한 폴리우레탄은 소각하는 방법에 의하여 처리한다고 하여도 매연, 악취 및 그 독성(포스겐가스)과 함께 유발되는 탄소의 형성으로 인해 제2의 환경공해를 유발하기 때문에 소각에 의한 처리는 불가능하다.Even if such a polyurethane is treated by incineration, it is impossible to treat by incineration because it causes a second environmental pollution due to the formation of carbon caused by soot, odor and its toxicity (phosgene gas).
이러한 문제점을 다소나마 털기 위하여 매립 또는 이와유사한 형태로 처리한다고 하여도 부식이 되지 아니하는 물질이므로 환경적 차원에서 상당한 물의를 일으키고 있는 문제점을 안고 있다.In order to remove some of these problems, it is a material that does not corrode even if it is treated in a landfill or similar form.
본 발명은 이러한 문제점 덩어리인 폐폴리우레탄을 재생하여 건축자재로 사용할 수 있는 연구를 거듭하던중 본 발명을 창출할 수 있었다.The present invention was able to create the present invention while repeating the research that can be used as a building material by recycling the waste polyurethane which is such a problem mass.
본 발명은 폐폴리우레탄을 특정한 물질과 결합시켜 이를 공극이 발생되지 않도록 팽창함으로써, 훌륭한 건축용 단열재 및 방음처리를 할 수 있는 단열재를 제조할 수 있었는바, 이하 첨부된 도면 제1도에 의하여 본 발명에서 폐폴리우레탄을 재생하여 단열재를 제조하기 까지의 공정을 상세히 설명하면 다음과 같다.According to the present invention, by combining waste polyurethane with a specific material and expanding it to prevent voids, it is possible to produce a good building insulation and sound insulation which can be soundproofed. In the following describes in detail the process up to recycle the waste polyurethane to produce a heat insulating material.
먼저 통상의 폐폴리우레탄을 수거 및 선별하는 수집공정을 거쳐서 수거 및 선별된 폐폴리우레탄을 분쇄하는 분쇄공정을 취한다.First, a grinding step of pulverizing the collected and sorted waste polyurethane is carried out through a collecting step of collecting and sorting ordinary waste polyurethane.
이때 분쇄된 폐폴리우레탄의 직경은 거의 분말형태에서 5mm이하로 분쇄한다.At this time, the diameter of the pulverized waste polyurethane is pulverized to about 5mm or less in the form of powder.
이러한 분쇄공정에서 분쇄된 폐폴리우레탄의 크기가 5mm이상이되면 완제품인 단열재를 성형할 때 공극이 발생하여 단열효과가 떨어지는 문제점이 있으므로 5mm이하의 크기로 분쇄한다.If the size of the waste polyurethane pulverized in such a crushing process is 5mm or more, when forming the insulating material as a finished product, there is a problem that a gap occurs when the insulation is inferior, so it is pulverized to 5mm or less.
이러한 분쇄공정에 의하여 분쇄된 폐폴리우레탄을 이송하는 이송공정을 거쳐 포집하여 두는 포집단계인 포집공정을 취한다.It takes a collecting step, which is a collecting step of collecting the waste polyurethane pulverized by such a grinding step through a transfer step.
이렇게 포집된 분쇄폴리우레탄은 폴리우레탄원액, 경화제, 프레온원액 및 물과 혼합하는 혼합공정을 취하게 된다.The pulverized polyurethane thus collected takes a mixing step of mixing with a polyurethane stock solution, a curing agent, a freon stock solution and water.
이때 분쇄한 폐폴리우레탄 100wt%당, 폴리우레탄원액(MDI : 메틸렌비스페닐이소시아네이트)을 8~5wt%, 경화제인 메칠크로라이드(MC)를 4~1wt%, 액화프레온(CFC)을 3~1wt% 및 물을 3~1wt%을 혼합한다.At this time, per 100wt% of the pulverized waste polyurethane, 8 ~ 5wt% of polyurethane stock solution (MDI: methylenebisphenylisocyanate), 4 ~ 1wt% of methyl chloroide (MC) which is a curing agent, and 3 ~ 1wt of liquefied freon (CFC) Mix 3-1 wt% of% and water.
상기한 혼합공정에서 분쇄된 폐폴리우레탄 100wt%당 혼합되는 폴리우레탄원액(DMDI)이 8wt%이상으로 혼합하게되면 완제품의 열전도율이 크게 증가되는 단점을 보였는데 본 발명에서 단열재 또는 방음재에서 열전도율이 증가한다는 것은 단열효과 및 방음효과를 득하지 못한다는 결론에 이르게 되고, 또한 폴리우레탄원액이 3wt%이하로 혼합하게 되면 완제품의 성형시 팽창계수가 극히 떨어지게 되어 체적의 변화가 발생하지 않기 때문에 완제품의 무게가 중량화 및 고형화가 즉시 도래하는 단점이 있게된다.When the mixed polyurethane stock solution (DMDI) mixed per 100wt% of the waste polyurethane pulverized in the above mixing process was 8wt% or more, the thermal conductivity of the finished product was greatly increased. In the present invention, the thermal conductivity of the insulation or soundproof material is increased. This leads to the conclusion that the insulation and sound insulation effects are not obtained, and when the polyurethane stock solution is mixed at 3wt% or less, the expansion coefficient is extremely low when forming the finished product, and thus the volume change of the finished product does not occur. There is a drawback that weighting and solidification immediately arrive.
또한 경화제(본 발명에서는 메칠크로라이드를 사용)를 분쇄된 폐폴리우레탄 100wt%당 혼합되는 경화제(메칠크로라이드)가 8wt%이상 혼합하게되면 분쇄된 폐폴리우레탄과 분쇄된 폐폴리우레탄간의 경화속도가 지극히 빨라서 폐폴리우레탄이 본 발명에서 억제하고자 하는 팽창체적이 있기전에 이미 경화되어 버리는 단점이 있고, 또한 경화제(메칠크로라이드)가 1wt%이하가 혼합되게 되면 본 발명에서 억제하고자 하는 만큼의 폐폴리우레탄의 팽창이 충분히 있었음에도 불구하고 분쇄된 폴리우레탄과 분쇄된 폴리우레탄사이에서 경화가 지극히 늦게 발생하는 문제점이 있게 된다.In addition, when the curing agent (methyl chloride is used in the present invention) is mixed with more than 8wt% of the curing agent (methyl chloride) mixed per 100wt% of the crushed waste polyurethane, the curing speed between the crushed waste polyurethane and the crushed waste polyurethane is It is extremely fast so that the waste polyurethane is already cured before there is an expansion volume to be suppressed in the present invention, and when 1 wt% or less of the curing agent (methyl chromide) is mixed, as much waste as is desired to be suppressed in the present invention. Although there is sufficient expansion of the polyurethane, there is a problem that curing occurs extremely late between the pulverized polyurethane and the pulverized polyurethane.
또한 프레온(CFC)는 분쇄된 폐폴리우레탄 100wt%당 3wt%에서 1wt%범위에서 혼합되게 되는데,In addition, Freon (CFC) is mixed in the range of 3wt% to 1wt% per 100wt% of the crushed waste polyurethane,
3wt%이상되면 분쇄된 폐폴리우레탄의 팽창이 급격히 발생하여 경화도 되기 전에 팽창에 의해서 발생된 공극에 의해 단열효과가 떨어지는 문제점이 있었고, 1wt%가되면 폐폴리우레탄의 팽창속도가 극히 떨어져서 장시간의 생산시간을 요하는 단점이 있었다.If more than 3wt%, the expansion of the pulverized waste polyurethane occurs rapidly, and there is a problem that the thermal insulation effect is lowered by the voids generated by the expansion before hardening, and if it is 1wt%, the expansion rate of the waste polyurethane is extremely low, There was a drawback to the production time.
이렇게 혼합공정에서 혼합된 혼합폴리우레탄은 일정한 체적을 가진 지그(Zig)에 공급하여 지그(Zig)의 향상, 모양에 따라 성형하는 성형공정을 취하게된다.In this way, the mixed polyurethane mixed in the mixing process is supplied to a jig having a constant volume to take a molding step of improving the shape and shape of the jig.
본 발명의 성형공정에 사용되는 지그(Zig)는 완전밀폐가 될 수 있을 뿐만 아니라 개구부가 내부의 압력에 의해 탈거되지 않도록 강하게 지지할수 있는 것이어야 한다.Zig used in the molding process of the present invention should be not only completely sealed but also able to be strongly supported so that the opening is not removed by the pressure inside.
이러한 지그(Zig)에 상기한 바 있는 혼합폐폴리우레탄을 충전하여야 할 때에는 지그(Zig)전체체적의 ½ ~ ⅓ 의 양만큼 충전하여 준다.When the above-mentioned mixed waste polyurethane is to be filled in the above-mentioned jigs, the amount of the entire zig is filled by ½ to ⅓.
이렇게 지그(Zig)의 전체체적의 ½ ~ ⅓을 충전한 상태에서 열처리를 취하여 주는 열처리공정을 취한다.In this way, a heat treatment process is performed in which the heat treatment is performed in a state in which ½ to ⅓ of the total volume of the zig is filled.
이러한 열처리공정은 통상은 히팅룸(Hcating Room)내에 상기한 지그(Zig)를 적재하여 건조된 가열공기로 취한다.This heat treatment step is usually taken as heated air by loading the above-mentioned jig (Zig) in a heating room (Hcating Room).
이때 상기의 가열공기의 온도는 30~40℃를 유지해야 한다.At this time, the temperature of the heating air should be maintained at 30 ~ 40 ℃.
이러한 열처리공정을 취하게되면 혼합폐폴리우레탄이 지그내에서 팽창을 하게되는데, 그 팽창률이 지그에 의하여 제한됨을 알수 있다.When the heat treatment process is performed, the mixed waste polyurethane expands in the jig, and the expansion rate is limited by the jig.
즉 혼합폐폴리우레탄이 지그의 전체적인중 ½ ~ ⅓이 충전되는 것이므로 충전된 혼합폐폴리우레탄은 지그내에서 완전히 팽창하였다고하면 최초충전된 량의 200~300%만큼 팽창 한 것이된다.That is, the mixed waste polyurethane is filled with ½ ~ 중 of the overall of the jig, so that the mixed mixed polyurethane filled is expanded by 200 to 300% of the initial charged amount.
이때 혼합폐폴리우레탄의 충전을 200%이하로 팽창시키게 되면 완제품이 중량화 될뿐만아니라 완전히 고형화 하기 위해서는 상당한 시간 동안 열처리해야 하는 문제점이 있어서 경제성 및 건축물에 시공하기 위해 가공하고자 할 때 가공성이 떨어지는 단점이 있었고, 300%이상으로 팽창시키게 되면 혼합폐폴리우레탄과 혼합폐폴리우레탄사이에서 공극이 크게 발생하여 열전도율이 높아 단열 및 방음재로 사용하기 적합하지 아니한 단점이 있었다.In this case, when the filling of mixed waste polyurethane is expanded to 200% or less, the finished product is not only weighted but also has to be heat-treated for a considerable time in order to be completely solid. When expanded to more than 300%, there was a disadvantage that a large gap occurs between the mixed waste polyurethane and the mixed waste polyurethane, the thermal conductivity is not suitable for use as a heat insulating and soundproofing material.
따라서 혼합폐폴리우레탄을 지그의 전체체적의 ½ ~ ⅓의 량만큼충전하여 지그에 의하여 강제로 혼합폐폴리우레탄을 200~300%만 팽창시켜주는 것이 가장 적합하였다.Therefore, it is most suitable to charge the mixed waste polyurethane by the amount of ½ ~ 지 of the total volume of the jig and force the mixed waste polyurethane to expand by only 200 to 300% by the jig.
또한 열처리공정을 취할 때 공급되는 건조된 가열공기의 온도가 30℃이하로 유지하게 되면 혼합된 폴리우레탄의 화학반응의 지연으로 인해 팽창이 지극히 늦고 또한 폐폴리우레탄의 팽창성질이 감소하여 완제품이 중량화 되는 단점이 있었다.In addition, if the temperature of the dried heated air supplied during the heat treatment process is maintained at 30 ° C. or lower, the expansion is extremely slow due to the delay of the chemical reaction of the mixed polyurethane, and the expandability of the waste polyurethane is decreased. There was a disadvantage of becoming.
또한 40℃이상을 유지하게 되면 화학반응의 급격한 활동으로 인해 액화프레온등의 기화성물질에 의한 폭발등의 안전성의 문제점과 함께 폐폴리우레탄의 빠른 팽창으로 인해 조직 즉 형질의 변화에 의해 단열, 방음이 효과가 떨어지는 단점이 있었다.In addition, if it is maintained above 40 ℃, due to the rapid activity of the chemical reaction, safety problems such as explosion caused by vaporizing substances such as liquefied freon, and due to rapid expansion of the waste polyurethane, insulation, sound insulation due to the change of tissue, trait, etc. There was a downside to the effect.
이러한 열처리공정은 통상3시간 정도하는 것이 적합하였는데 이는 상기한 지그내에서 화학반응이 3시간 정도까지 계속하여 발생하였고, 이러한 것은 폐폴리우레탄이 3시간 지난시점에까지 팽창을 하고 있는 것에 의해 알수 있었다.The heat treatment process was suitably performed for about 3 hours. This was because the chemical reaction occurred continuously for about 3 hours in the above-mentioned jig, which was confirmed by the expansion of the waste polyurethane up to the point of 3 hours.
그러나 본 발명에서는 지그의 전체체적의 ½ ~ ⅓ 정도의 혼합폐폴리우레탄을 충전하여 팽창시키므로 약 3시간이 흐른 시점에서 충전된 혼합폐폴리우레탄의 부피가 200~300%로 팽창하였으므로 단열 및 방음의 효과를 위해서는 상기한 조건이 가장 양호한 것임을 알 수 있었다.In the present invention, however, the mixed waste polyurethane of ½ ~ ⅓ of the overall volume of the jig is filled and expanded so that the volume of the mixed waste polyurethane filled at about 3 hours is expanded to 200 to 300%, so that the insulation and sound insulation It was found that the above conditions were the most favorable for the effect.
이러한 열처리공정을 마친 다음 상온하에 방치하여서 완전히 고형화 하는 냉각공정을 취한다.After finishing the heat treatment process, it is left to stand at room temperature to take a cooling process to completely solidify.
이때 냉각공정은 30℃의 이상의 온도가 되면 계속하여 화학반응이 일어나게 되므로 30℃이하의 온도에서 취하며 10℃이하에서 냉각공정을 취하게 되면 완전히 고형화 되기전에 팽창한 것이 오히려 수축하게 되는 단점이 있었다.At this time, the cooling process takes place at the temperature below 30 ℃ and the chemical reaction occurs continuously when the temperature is over 30 ℃. If the cooling process is taken below 10 ℃, the expanded process will shrink rather than completely solidified. .
이러한 온도에서 24여시간동안 방치하여 완전히 고형화한 다음 지그를 탈거하여 완제품을 수득하는 수거공정을 취하여 필요에 따라 단열 또는 방음의 목적에 따라 사용하면 될 것이다.It may be left at this temperature for 24 hours to completely solidify and then take off a jig to remove the finished product to obtain a finished product and use it for the purpose of insulation or sound insulation as necessary.
한편 상기한 본 발명에 의하여 제조된 단열재와 종래부터 단열 및 방음의 목적으로 사용한 것을 서로 열전도율 시험하여 보았더니 본 발명에 의한 제품이 열전도율이 낮아 단열효과가 뛰어남을 알 수 있었다.On the other hand, when the thermal conductivity test prepared according to the present invention and those conventionally used for the purpose of thermal insulation and sound insulation were tested with each other, the product according to the present invention was found to have excellent thermal insulation effect due to low thermal conductivity.
